Description

Container and pressure sealing closure combination
The present invention relates to a kind of sealing member and container combination system, be specifically related to utilize the internal pressure of container contents to realize the leak free sealing member.
For cost and safety factor, people wish to make the container of adorning CO 2 aerated beverage with polyethylene terephthalate (PET) very much.Benefit with PET is its repeated usage easily.But according to present design, the carbonated beverage container itself is the screw thread mouth of doing with PET and have a dress aluminium lid.Aluminium lid or closure member have the annular perforations that forms a defiber, so after lid took off from container, lid just stayed the thin aluminium ring of a circle.
Therefore utilize again in the process certain the time, just need the aluminium ring is separated with the PET material.If entire container closure member coupling system can be made with PET, then do not have this separating step.Because PET has different intensity with aluminium, so need the different closure member shape of design.An example of this closure member and container is disclosed in the US-A3825114 of Wiedmer.This patent disclosure a kind of container-closure that is used to seal the bottle that the pressure content is housed, and comprise a sealing member, but the sealing part has the integrated disc portions of deformation, shape is outwards recessed.This integrated disc portions responds the internal pressure of container contents and produces deformation.Yet the closure member of this gentle shape is not suitable for the assembling of PET, because the internal pressure of representative type carbonated beverage container can be greatly to the whole surface deformation that makes this closure member.
Therefore, need a kind of design that is suitable for the container and the closure member of carbonated beverage, in this design, closure member can be used such as the flexiplast of PET and make.In addition, the shortcoming of this closure member is that they lack the device that discharges container inner pressure gradually.Therefore, can be dangerous when opening this prior art closure member, because the pressure seal spare of content will spray from container in the container.Therefore need a kind of container and enclosed piece mechanism, in this mechanism, the internal pressure of utilizing container contents to produce realizes sealing, and provides a kind of device to come equilibrium of pressure gradually during opening sealing member.
The present invention is a kind of container and pressure sealing closure combination, and this system makes of PET fully, and closure member utilizes the pressure that content is produced in the container to realize sealing.Closure member be configured as the annular mouth that covers container and comprise the flange portion that meshes vessel port, substantially for the middle body of firm shape with make flange and the interconnective annular elbow loop section of middle body.Content internal pressure in the middle body response container and the upward movement that produces rotates the elbow loop section promotes flange portion thus to be pressed against radially outwardly on the vessel port substantially, thereby realizes sealing.In addition, vessel port comprises the annular groove of an outside, and the flange portion of closure member comprises the fin of this groove of engagement, thereby provides another that closure member is fixed to mechanism on the container.
Vessel port comprises an inner periphery that extends axially groove, and this groove is on the interface between flange portion and the vessel port.When closure member during taking off from container deformation took place, the pressed gas in the container just can flow to the external world by these grooves, and this groove has been regulated the outflow of gas in the container, had prevented the explosivity ejection of gas when opening.
For ease of taking off closure member from container, closure member has a sheet that pulls that radially protrudes from the closure member edge.Therefore, pull sheet with respect to the closure member rotation and just can remove closure member, this pulls sheet and makes the closure member distortion and the pressed gas in the container is overflowed, and has eliminated thus by the elbow loop section and has been pressed against the sealing mechanism that flange portion produces.In preferential embodiment, closure member comprises several groups of notches that radially extend, when closure member is out of shape when opening closure member, and this notch fracture.This fracture helps the further deformation of closure member and removes from container.In addition, the evidence that the line of rupture that is caused by the fracture notch provides a kind of container of seeing easily to be opened can prevent to seal this container with that specific closure member again.
In addition, in preferential embodiment, container also comprises a base or bottom, and this bottom comprises an annulus.The size of this ring is prescribed to such an extent that lay closure member in the mode of slight force fit in the circumference within it.Thereby ought take off rear enclosed spare from container and just can be stored on the bottom, container and closure member can be used as one unit and handle.
In a commutable embodiment, the elbow loop section be changed and comprise one radially outward with upwardly extending wedge.When central authorities partly are subjected to the effect of container inner pressure content and when being offset, wedge-like portion is just rotated and contacted with flange portion, thereby realize sealing.
The purpose of this invention is to provide a kind of container and closure member coupling system, this system can adapt to for example needs of carbonated beverage of container contents; This system can preserve the content of pressure safely and make with PET fully; The internal pressure that this system utilizes container contents to produce is implemented in the sealing between container and the closure member; Closure member engagement container in this system makes the release that can regulate pressed gas in the container during opening closure member safely; Form the notch of line of rupture during closure member is included in and opens in this system, so that open and prove that closure member takes off from container; Container in this system comprises a bottom that is suitable for laying closure member, makes closure member can be stored in steadily in the bottom after taking off from container; Container in this system and closure member are made quite easily and are installed.

As Fig. 1, shown in 2 and 3, container of the present invention and pressure sealing bounded system comprise and are roughly columnar container 20 that this container has by closure member 24 leak free vessel port 22.Container 20 and closure member 24 all adopt reusable material, and the most handy polyethylene terephthalate (PET) is made.
Closure member 24 comprises flange portion 26, the circular middle body 28 of rising and makes flange portion and the interconnective elbow loop section 30 of middle body.Flange portion 26 comprises vertically extending radial outer wall 32, vertically extending inner radial wall 34 and the horizontally extending interconnective roof 36 of this inner and outer wall that makes of cardinal principle.Pull sheet 38 and outer wall 32 monolithic moldings, and extend radially outwardly from outer wall 32.
Container 20 comprises frusto-conical portion 40, central cylindrical portions may 42 and ends at the following frusto-conical portion 46 of circular bottom part 46.Last frusto-conical portion 40 upwards ends at (see figure 4) in the vessel port 22.
Shown in Figure 4 and 5, middle body 28 comprises the circumferential flange 48 of a thickening, and this flange green phase is worked as thin hinge 50 and is connected on the elbow loop section 30.Equally, elbow loop section 30 green phases ought be connected on the inwall 34 by the second thin hinge fraction 52.Thereby the elbow loop section can rotate with respect to middle body 28 and inwall 34.In addition, elbow loop section 30 makes progress shape at an angle with respect to middle body 28, makes middle body and elbow loop section constitute the shape that is roughly plate.
The inwall 34 of flange portion 26 is also seen Fig. 6 at its lower edge 54() thickeied, and the outside face 56 of inwall 34 direction from vessel port 22 to the inherence that leave radial shape is coning gradually.The joint portion 58 of inwall 34 and end wall 36 is quite thin, so that crooked easily when vessel port 22 is removed closure member 24.On the contrary, 60 of the inner radial surface of vessel port 22 inwardly shorten circular cone gradually into, and its cone angle cardinal principle equates with the tapering of the outside face of inwall 34.In addition, inside face 60 comprises many axially extended notches 62, and this notch is along the circumference configuration of vessel port 22, and spacing equates (also seeing Fig. 2) substantially.The existence of notch 62 provides the passage of pressed gas outflow in the container 20.Notch 62 forms between a series of flanges that separate 64, and this flange forms on the inside face 60 of vessel port 22.
As shown in Figure 4, vessel port 22 comprises a undercut that forms annular groove 66, and this groove is along the circumferential extension of the outside face 68 of vessel port 22.The outer wall 32 of flange portion 26 comprise one be configured as can with the radially inner fin 70 of groove 66 ingears.As shown in Figure 5, fin 70 continuously along the circumferential extension of outer wall 32, is only disconnected by four total breaking portions by 72 expressions basically.Breaking portion 72 with pull sheet 38, a position and two midways location on the flange portion just in time relative with pulling sheet 26 overlap, these two midways location are positioned on the flange portion 26, and become about 77 ° angle with respect to the breaking portion that pulls sheet 38.Each breaking portion 72 comprises a pair of notch 74,76 that forms in outer wall 32 and roof 36 downsides that separates.This part of between notch 74,76, extending except with pull the breaking portion that sheet 38 combines outside do not have fin 70.
As shown in Figure 4, closure member 24 pressure that partly is applied to closure member 24 by the content (not shown) that pressure is arranged by container 20 makes on its vessel port that leans against container 20 22 and is sealed.The internal pressure that is higher than atmospheric container 20 acts on an outside power in the direction of arrow A on the middle body 28 of closure member 24.Middle body 28 these power of response and inwall 34 that the motion that makes progress a little makes middle body face toward flange portion 26 outwards rotates elbow loop sections 30.The outside face 56 that this rotation promotes inwall 34 then is pressed on the inside face 60 of vessel port 22.The intrinsic hoop strength of vessel port 2 will stop deformation, be enough to make container contents or power closure member 24 can be enclosed on the vessel port 22.
This motion also is subjected to the opposite conical ingear restriction between the inside face 60 of the outside face 56 of inwall 34 and vessel port 22.The part 54 of the thickening of inwall 34 contacts (also seeing Fig. 7) at sealing area 78 with the inside face 60 of vessel port 22.Sealing area 78 stops the content that pressure is arranged in the container 20 from outlet effusion (see figure 1).
Operation from vessel port 22 is removed closure member 24 is shown in Fig. 7-9 according to priority.As shown in Figure 7, closure member 24 is fixedly mounted in container 20(and sees Fig. 1) vessel port 22 on, wherein, the inwall 34 of flange portion 26 is compressed against on the inside face 60 of vessel port 22.In addition, fin 70 locking meshes of outer wall 32 are on the groove on the vessel port 22 66.
As shown in Figure 8, pull sheet 38 when the direction of arrow B is rotated when making, just 58 rotations of outer wall 32 and roof 36 around the joint portion, thereby near just disengagement from groove 66 of the fin that pulls sheet 38.Simultaneously, because this rotation, roof 36 and inwall 34 just depart from vessel port 22.This also makes the part 54 of thickening move on on the flange 64 on the inside face 60 of vessel port 22 from sealing area 78.When this position, the content of container 20 just can be seen Fig. 2 by notch 62() flow out.
As shown in Figure 9, the further skew that pulls sheet 38 causes the zone of outer wall 32 along notch 74,76 fractures that pulling sheet (also seeing Fig. 5) both sides.When container 20 is removed closure member 24, other breaking portion 72 also will split along its corresponding mouthful 74,76.The partial destruction of this closure member 24 can prevent from closure member is contained on the container 20 and again again closure member is sealed on the container 20 again.
